(1) The camera should be installed in a place near the monitoring target that is not easily damaged by the outside. Installation height, indoors from the ground 2.5 ~ 5m; outdoor from the ground 3.5 ~ 10m, not less than 3.5m.
(2) The camera in the elevator car shall be installed at the top of the elevator at the opposite corner of the elevator operator; the optical axis of the camera shall be at an angle of 45° to the two walls of the elevator and at a 45° angle to the ceiling of the elevator.
(3) The camera lens should be aligned with the monitoring target in the direction of the light source.
(4) The camera lens should be protected from direct sunlight to ensure that the target surface of the camera tube is not damaged; there should be no objects in the field of view of the lens that block the target.
The specific practice can refer to the 97×700 intelligent building weak electricity engineering design and construction atlas.
